Breather, a startup in the on-demand economy, offers a unique solution to the modern challenge of finding quiet, comfortable spaces in bustling urban environments. Unlike tech giants focused on user acquisition, Breather emphasizes supply, creating a network of professional yet welcoming spaces bookable on-demand. Beginning in Montreal, the company learned to optimize their supply network by ensuring spaces were within a walkable distance, providing consistency and a predictable experience, akin to Starbucks. This strategy allowed Breather to effectively expand into major cities like New York, Boston, and San Francisco, maintaining a strong local network effect. By focusing on supply-side dynamics and maintaining a uniform user experience, Breather has successfully scaled its operations, demonstrating the viability of its business model as it plans further expansion to cities like London and Los Angeles, continuing to offer peace and quiet to urban dwellers.
